Johnni Winther 0a9e57419b [kernel] Make verbose qualified names conditional in toStringInternal 
Including the library name/uri in types and member names makes these
unreadable in most cases. This changes that default toStringInternal
to omit the library name/uri but supports a verbose mode that includes
the library name/uri for debugging the rare occasions where they matter.

The interpretation of the subtype check result depends on the mode.  In partial
NNBD mode all type errors that wouldn't be errors in non-NNBD programs should
become warnings.  In full NNBD mode all such errors are errors.  This CL adds
the mode explicitly to the interface of the subtype check as a parameter.

Kevin Millikin 796d628ab6 Improve error reporting from Kernel scripts 
* Ensure that we have a .dill file and it has the correct version before
  we start decoding it in dump.dart.

* Throw errors, not strings.  Ensure that they have a useful
  toString().

* Do not print usage except when the command is invoked
  incorrectly (wrong number of arguments).  Once we get into the
  command it's less likely that it's been invoked incorrectly and more
  likely that something else has gone wrong.

  Because these utilities are invoked from other scripts (like the
  fasta command), printing their usage for problems other than
  invoking them correctly doesn't match the way that they were invoked
  and it's confusing.

Alexander Aprelev c339846594 [kernel] Move util.dart from bin to lib. 
bin/util.dart doesn't have main() entry point and that breaks snapshot generation that is
automatically invoked by pub for all dart sources in bin/ folder.
